FIELD OF THE INVENTION

The invention is directed to the field of cargo transportation and more particularly to a smart cargo container system comprising secure (strong and lockable), sealable, stackable, auditable, pollable, and trackable, universal, “pallet boxes” that may be used in two main ways: 1) auto-latchingly secured to the undercarriage transverse I-beams of over-the-road semi-trailers by means of a guiding latching system; and 2) stackable, up to three or more high, inside the trailer bodies and in warehouses and at customer locations. Sophisticated electronic locks, sensors and alarms are provided, as well as an RF communications and GPS locator module that radios to a base station the time, location and status of the inventive smart cargo container, and any anomalous events as they occur, including unauthorized attempts to open or break into the container, or potential damage events such as fire, exposure to high temperature, radiation, biological contaminants, unauthorized movement, shock and the like. In addition, both the locks and comm modules are programmable, and provide extensive, and selectably pollable and downloadable event, access and transport history and audit trails. The comm system permits remote tracking and real time status check via the Internet, LAN or WAN wireless networks.

BACKGROUND OF THE ART

A variety of cargo container systems have been proposed in the prior art but have not developed into a universal system for cargo transport that answers the complex needs of both shipping customers and the trucking industry.

Companies typically budget 2-4% of the value of a shipment for loss due to theft in transit. A typical type of petty theft occurs from a stacked pallet of merchandise in corrugated containers. A thief will cut or punch a hole in an exposed side of a box, remove some merchandise and then rotate the box to conceal the damaged side. Typical loading dock check-in procedures merely confirm the receipt of a number of pallets containing a number of cartons. Since the time and location of the loss cannot be determined at the time of discovery by simple external inspection, no recovery attempt is made. Such theft losses also occur in the warehouses and back rooms of retailers and wholesalers.

Another common and accepted form of loss is in-transit damage. When items are shipped in corrugated boxes on pallets it is very common for the boxes to sustain corner and end damage that renders them unsuitable for full value retail sale. Many wholesalers and distributors offer a level of claim for damages of 1 to 2% that will be honored without requiring return of goods. These low-level claims are frequently taken as an automatic discount by retailers regardless of the condition of the goods they receive. Additionally, much larger losses due to damage during shipment are not uncommon. Management of such large damage claims, which require return of goods as proof of damage, are very costly. They entail additional shipping costs and substantial administrative overhead, as well as genuine cost of goods due to product loss.

The American Trucking Association reports that the average Class 8 truck having a permitted load capacity of 60,000-90,000 pounds, actually carries a haul weight on average of just under 29,000 pounds (source: ATA Trucking Trends 2000). This represents an underutilization of the truck's hauling capacity in weight of more than 50% on average. The reasons for this are two-fold. First, in some cases, owing to the density of the materials being shipped, the truck simply fills (cubes out) before the weight limit is reached. In this instance undercarriage usage could provide immediate benefit because it effectively increases the carrying volume of the trailer. Second, in other cases, the structural strength of the cargo as packed on un-reinforced pallets does not allow the cargo to be stacked at all, or in other cases does not allow the cargo to be stacked to the full interior height of the trailer.

Accordingly, this exemplary state of the art reveals that there remains a significant and substantial unmet need for universal, fully closeable and lockable pallet containers for secure shipment of a wide range of goods, both interior of the trailer for improved security and under-slung to maximize the unused, permitted carrying capacity of trucks.

THE INVENTION

The invention comprises a smart, pallet-box type cargo container system employing secure (fully closeable and lockable), sealable, stackable, auditable and trackable (via GPS), universal, “pallet boxes” that are used in two main ways: 1) auto-latchingly secured to the under-carriage transverse I-beams of over-the-road semi-trailers by means of alignment and hanger assemblies that guide and latch the pallet boxes securely in place for transport; and 2) stackable, up to three or more high, inside trailer bodies, in warehouses and at customer sites.

As set forth in our co-pending application Ser. No. 10/940,447, the inventive pallet boxes are designed to be optionally secured by hanger/latching assemblies unique to, and retrofittable-on, most types of semi-trailer undercarriages, both US and metric (European, Central and South American, and Asian) standard dimensions. The pallet boxes may be refrigerated, insulated, or atmospherically controlled, e.g., chargeable with preservative, security or disinfecting gases, during shipping.

For both the under-slung and in-trailer-stacked mode embodiments, by way of example, the inventive universal smart cargo containers may be any convenient size, and preferably are typically on the order of 48″ deep×40″ wide×30″ high in size to provide 35 cu. foot capacity. Half-size 24″×40″ smart cargo containers are also particularly useful for in-store use, permitting sale directly out of the inventive containers. The box dimensions may be varied depending on trailer undercarriage and interior dimensions, and is preferably selected so that the height, in multiples of 2-6, permits stacking inside the trailer body with enough top clearance to permit sufficient lifting by a forklift so the feet clear the feet-bosses of the box on which it is resting.

The pallet boxes by way of example, may be constructed of any high strength material, and are preferably unitary. Preferred box/bin materials include steel, fiberglass, high strength homopolymers or copolymers, laminated or reinforced polymers (such as carbon and/or glass fiber reinforced polymers), high-density co-molded polyolyfin and steel, or any other available suitable rugged material, available at the present or in the future. It is preferred that a pallet box is capable of carrying from 2000#-3000#, and is capable of withstanding the weight of at least two additional fully-loaded pallet boxes stacked on top of it.

As set forth in our co-pending Ser. No. 10/940,447, optionally, pallet boxes are attached and locked to the semi-trailer under-floor girder I-beams through alignment and hanger hardware. In a preferred embodiment, J-hooks on the hanger assembly engage locking pins on the sides of the pallet boxes, and as the box is raised, the J-hooks rotate into a locked position. In the process, box lid is preferably compressed to assist in keeping it sealed and inaccessible during transport.

In the preferred embodiment, the pallet boxes include an exterior reinforcement structure of fabricated steel, termed an “exoskeleton”, that functions to provide: 1) structural strength for stacking and support of the boxes when hung under the trailer; 2) attachment points for retaining the boxes when hung under the trailer bed; and 3) fortification of the box against unauthorized entry for security purposes. Steel “flat” or strapping criss-crosses the lid (4″-6″ spacing between adjacent straps) and may align with vertical channels along at least two opposed vertical sidewalls (preferably end walls) of the box. The vertical channels extend to strapping under the floor. Spaced box feet provide apertures for access of the forks of a forklift from any side. A front side includes a lock mechanism with a pivoting, flanged lock cover.

A two-panel, two-hinge top lid is provided for the container, one set of hinges at the midpoint, and the other at the rear as an aid in loading and unloading the box. This permits the front half of the lid to be opened and folded back onto the rear half, and then the folded lid parts to be raised at the back hinge to open the back half of the container. The folded lid in the open position rests in a vertical, but backwardly canted position at the back of the container. This two-panel construction reduces the opening effort and the clearance above the container for opening. In the alternative, the lid could be hinged along the side as a single piece, with the locking assembly on the side opposite the side mounted hinges.

The top is also armored with exoskeleton strapping extending the longitudinal length of the lid and transversely across it. In addition, the lid overhangs the top to protect from fluid entry, and the marginal vertical edge of the lip includes a steel band for strength and security. Notched latch plates that engage grooved studs secured to the side of the box at the mid-point hinges function as anti-pry-open lid locks. The front of the lid includes a pair of slotted tangs that are engaged by cam-type locks on the front side adjacent the top. The underside of the lid includes a wide seal strip adjacent and all around the margin that is aligned with the box side top edges. Thus, when the top is latched and locked, the seal strip is compressed providing a hermetic seal between the box top and side walls of the box. The underside of the lid includes a variety of reinforcing recesses in which various sensors can be disposed. The top corners of the lid includes raised triangular bosses that mate with similarly oriented recesses in the feet of a box stacked on the top of it to prevent the stacked box from sliding during transport.

Additional strapping extends under the box floor so that the steel flat under-box strapping in conjunction with the channels to which the strapping is secured acts as a sling or harness. The box strapping is provided in three panels, a front and a back that are hinged to a bottom panel. Thus, the boxes when loaded under the truck are in fact slung from the J-hooks of the hanger assembly. The steel flat or strapping on the end walls and bottom is typically ⅛″ thick stainless steel stock by 3-5″ wide; the optional hanger pins on the box ends are typically ⅜″-½″ diameter. The top strapping is typically 1-2″ wide stainless steel strapping ⅛″ thick.

The front steel sling exoskeleton panel of the inventive box included a housing for an electronic lock and a hinged, flanged cover that, when raised completely covers the lock body, and includes a latch plate with a hole that engages the lock plunger. In addition, a pair of spaced cam locks engage the lid strap tang slots and enables the lid to be cinched down, sealing the lid to the box. The cam locks are also completely covered by vertical channels in the lock cover plate. Thus, to resist tampering; there are no exposed parts that act as a purchase for a pry bar. The preferred lock system is a hardened electronic lock mechanism that permits identification of which “keyholder” (approved access person or organization) opens the lock(s), when the lock(s) is/are opened, and how long the lock(s) stay opened, and, optionally, the location. By way of example, a suitable electronic lock is the NexGen high security electronic lock, Model 65 series, provided by Medeco Inc. of Salem, Va., USA, a division of Hillenbrandt Industries, Inc.

The locks and keys are programmable, including both at a home base and in the field, and store several thousand downloadable access events to provide a full audit trail. The programming includes configuring the key to select the time, and by integration with the RF controller and GPS module in the box, the location at which the box can be opened. Thus, the boxes can be both authorized entry and destination restricted.

An important feature of the inventive pallet boxes is that they are each integrated (complete), and highly tamper resistant. That is, there are no loose parts that can be lost during use or storage, and the material is selected for strength to resist both casual and relatively concerted theft attempts. The lock is integrated in the exoskeleton, the top has hidden latch members, and the comm module includes location and sensor systems to provide real-time state of the container data.

The pallet design provides for stacking and racking in any warehouse environment. The box height and floor footprint are chosen to utilize the interior space of the industry standard trailer van when stacked three units high. The lids include bosses that mate with recesses in legs of boxes stacked on top of them so that they can be stacked only in identical orientation or 180° orientation (front over front, or front over back. The steel of the bottom panel exoskeleton includes downward flanges at each side of the front and back fork lift entries to both protect the feet from damage by fork lifts, and to transfer weight to the exoskeleton of the box below it on which it rests.

In addition, spaced feet on the bottom of the pallet boxes provide access between them for the forklift forks. These spaces are present in both horizontal axes in a manner to provide “four-way” accessibility. The loading is a two step process: 1) the forklift brings the closed, loaded pallet box under the truck bed, the guides aligning it as it is laterally placed under the truck, and 2) the fork lift then raising the box to engage the J-clamps, which may be spring-loaded to automatically engage the box fittings.

The pallet boxes have lids that are preferably provided with hermetic seals, for weather tightness and security. This feature provides security for the shipper and is of great benefit for shipping products requiring “privacy” and/or security, such as pharmaceuticals or mail.

Additional objects and advantages of the inventive system include the fact that attaching the weight to the undercarriage of the trailer lowers the center of gravity of the trailer. Thus, the incidences of roll-overs, fairly common in the trucking industry, are less likely to occur. Also, the inventive system provides substantial in-transit theft and damage reduction by virtue of the top being lockable and protected by the exoskeleton strapping and the tough bin wall material. As the inventive pallet boxes are universal in dimension, and include integral pallet-type forklift access, they can be left at the receiving retailer for storage until sale of the goods. Indeed, the inventive pallet boxes permit elimination of the shipping cartons, with the goods being sold directly out of pallet boxes. This reduces the carton cost, the carton packing cost, and the carton volume and weight. More product (goods) can be shipped in the inventive pallet boxes and the carton-related costs eliminated.

Another common and accepted form of transit loss that the invention would reduce is transit damage loss. The inventive rigid and reinforced, integral container substantially and significantly reduces the instance of real transit damage, as well as potentially allowing shippers to lower their thresh-hold for damaged goods claims of the automatic allowance category.

As to the truck hauling-capacity underutilization issue, the reinforced stacking strength of the inventive pallet boxes provides superior volume utilization of the interior cargo space by virtue of the stackability. If, even after stacking the interior of the trailer van, the truck is still under weight-capacity, further benefit is gained by use of the inventive pallet boxes in the under-slung mode. Further, the under-slung system may be used for fast delivery of partial loads, as the pallet box units can be location-dedicated, carrying single or mixed product loads. The speed and ease of unloading, without opening the main (rear) doors of the trailer permits small load distribution at an economically effective rate.

In connection with tracking and enhance security, each smart container is provided with a sensing communications module comprising sensors, controller, RF transceiver, GPS locator unit, battery and trickle charger. The sensors are distributed through the box and include a sensor screen system comprising conductive screen mesh adhered to the outside of thin, rigid inner box liner (of ABS plastic, for example) that is electrically connected to the controller. Other sensors are ultra-short range battery powered RF or hard wired sensors that report sensed condition data to the controller. The GPS unit inputs location data to the controller which sends out data burst transmissions on pager, cell phone or other network frequencies to relay stations or home base. Instead of the screen, one or more RF sensor(s) can be used to detect breaching of the container walls, top or bottom, such as a light detecting sensor that sends a signal to the controller if an aperture as small as a crack forms in any of the box walls.

The smart container data communication and management system includes sensors, locks, alarms, container armed status lights, data encoders, transmitters and/or transceivers, computer programs, data bases, and related equipment to enable activation, coding, decoding and use of the data communications system, including real time and past history display of status and location, and management and operation report generation. The inventive smart cargo container monitoring and management electronic data communications system includes container-mounted components, separate remote signal relays (towers and satellite), monitoring station components, and auxiliary equipment including locators (GPS locators) and locking systems. The home base monitoring station includes a computer system having a CPU in which is loaded data engine, display programs and web server or web browser programs to enable activation, operation and use by customers of the data system.

Each shipper, customer or other authorized tracker can access data on individual ones of the smart cargo containers or groups of them via a customer or user name and password on an SSL server webpage. The tracker can poll where the container is, and the location provided by the container's GPS/GSM unit will be displayed on a map. In addition, in the case of an anomalous condition being sensed, such as: unauthorized unlocking; attempt at tampering, entry or opening of the container; unlocking at an improper location; sensing temperature, humidity, chemical conditions, and the like, the home base or web site system will wake up and emit an alarm, including audio, visual, sending of e-mails, faxes and phone calls, to a selected number and type of individual for response. The remote monitoring aspects of the invention provides a method for shippers, customers, and security/audit personnel to monitor from a single “home” base, many containers simultaneously, the number ranging easily in the thousands. Under the inventive system, the tracking personnel can be notified and check when anomalous events occur and can have a complete handling report for each container from empty before loading to empty upon unloading at its destination, and with confidence in the security of the container along the route, including in the transport vehicle (truck, ship, rail, aircraft), in its origination facility, ware-houses or transfer depots along the way and to destination unload or storage.

The inventive security system provides a unique identifier for each container in the field that is radioed to home base when the container is first put in use. Each container is pre-configured at home base (e.g., home warehouse, customer or shipper facility, manufacturing facility or the like), or in the field via the PIC program with a unique identification number or other data (name of customer, shipper, type of goods permitted to be shipped, etc), and its cycle of time for status reporting is pre-selected at that time. After loading and closed, it is initialized or enabled, and thereafter the container reports its status, the time, or/and location back to home base on the predetermined timed cycle, e.g., every half-hour, more frequently at night, less during the day, etc.), or to pollers (very short range, long-life battery powered microprocessor-controlled RF transmitters that are placed at various sites around the warehouse, storage facility or customer location), or readers (long range, 100-1500′ depending on antenna) transceivers with the ability to receive an interpret the data from the container transponders and then forwarding this information by wired or wireless communication to a computer or computer network for real time location and status data retrieval from the containers). The program at home base displays a map from the map program with each container or group of containers located thereon with a unique icon, and the status can be indicated in text or change of icon, e.g., by animating the icon, changing color, flashing, change of text, combinations of them, and the like. In addition, an audio alert signal can be emitted on the computer speakers when the sensor or lock detects an anomalous event or unauthorized, untimely, or wrong destination attempts to open the container occur.

The inventive computer-based smart cargo container system permits complete management of the container security during transport, storage, loading and delivery, as a business, including communication via the Internet of container status and event reports, orders, billing, e-mail communications, and the like.

The controller/RF/GPS units are included in a module that is loaded in a special bay or recess in one of the legs of the box, or in other convenient location. A GPS unit can also be included in with the goods loaded therein at the time of sealing by the originating shipper or manufacturer. Customs or other security wires and seal systems may also be used. The lid lock may be programmable, e.g., activated by magnetic cards or keys, or of the push-button or dial type, to name a few examples.

It is preferred to include a loud, 60-100 DB battery-powered audio alarm system in the smart container. Preferably the alarm noise-maker is disposed in the front wall of the container behind a speaker grille. This alarm is activated by simple magnetic or button type contact switch elements in the lid and top of the box wall, respectively. The switch which arms or turns the alarm off is hidden behind the electronic lock cover plate. After unlocking the cover plate, the switch is accessible and is turned off so the top can be opened.

One skilled in the security art will appreciate that any desired level of security can be employed, dependent on the value and need, such as national security, anti-terrorist, intellectual property confidentiality, or other such need.

DETAILED DESCRIPTION, INCLUDING THE BEST MODES OF CARRYING OUT THE INVENTION

The following detailed description illustrates the invention by way of example, not by way of limitation of the scope, equivalents or principles of the invention. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best modes of carrying out the invention.

In this regard, the invention is illustrated in the several figures, and is of sufficient complexity that the many parts, interrelationships, and sub-combinations thereof simply cannot be fully illustrated in a single patent-type drawing. For clarity and conciseness, several of the drawings show in schematic, or omit, parts that are not essential in that drawing to a description of a particular feature, aspect or principle of the invention being disclosed. Thus, the best mode embodiment of one feature may be shown in one drawing, and the best mode of another feature will be called out in another drawing.

All publications, patents and applications cited in this specification are herein incorporated by reference as if each individual publication, patent or application had been expressly stated to be incorporated by reference.

FIG. 1 is a perspective view, partially schematic, of a long-haul truck of the tractor-trailer type showing the inventive smart pallet-box type cargo containers in both the under-slung transport mode and the in-trailer-stacked mode in the broken-away portion of the trailer. A long-haul truck10 of the tractor-trailer type is shown with inventivesmart cargo containers12 in both the under-slungmode14 secured to the undercarriage of thetrailer16, and the in-trailer mode18, the broken away section showingsmart containers12 stacked three-high. The under-slungmode14 shows asingle container12, with the positions of two more shown just aft of it in dashed outline. It can be seen that the currently unused space under the truck is efficiently utilized. Note that the location under the trailer does not appreciably increase the wind resistance, and indeed can serve to reduce the air turbulence created by the tractor wheels, which in turn can reduce blinding spray thrown up by the truck in rainy or snowy weather.

FIG. 2 shows a first, preferred embodiment of an inventivesmart cargo container12 in the closed and locked state. The container has a body and top, including afront side22, spacedside walls24,26, backside28, openable top30, and bottom32 with spacedfeet34 providingaccess36a,36b, and38a,38bfor four-way forklift access. The smart container can be handled in the same manner as a pallet, yet is secure both in storage and in transit, hence the inventive smart cargo container is also known as a “private” pallet box.

As compared to our prior application Ser. No. 10/330,149, the instant container includes security sensors, alarms, anti-pry latches, electronic locks and audit trail keys and communication systems. The access-controllable locking system is auditable, and the pallet-box type container is trackable and pollable to determine its security condition (or state) and its location, access and security condition history. Thus, those features together with its exoskeleton harness and lid locking and anti-pry system, the container is “smart” being both secure and “aware”, in that it can ascertain its location, condition and history throughout its use. An selected amount of memory capacity can be integrated in the electronics to provide an extensive auditable and downloadable history file; in that aspect of the functionality, the inventive smart container “knows” its handling history.

The front side of thesmart container22 preferably includes a two-panel top lid that is hinged at the back (seeFIG. 5) and at the mid-section42, to fold back and up (best seen inFIGS. 3-5) once thelock54 of the container is unlocked and theflanged lock cover56 is lowered. An exoskeleton-type load harness includes interlaced lid strapping44, lid edging66 and front, rear and bottom exoskeleton panels (80,82 and84, best seen inFIG. 6b). The front and rear panels includechannels50 and hinges at their bottom edges (best seen inFIG. 6b). In addition, for under-slung transport, the smart container optionally can includehanger brackets70 having pins that engage J-hooks or the like of the truck underbody hanger assembly, as set forth in our copending Ser. No. 10/940,447. The lid also preferably includesbosses52 that fit in recesses of the feet of a box stacked on top of it, to prevent shifting during transport (seeFIG. 6e).

FIG. 3 is an isometric view of the inventivesmart cargo container12 with the front half of thelid40aopened for access to theinterior load space62.Lock assembly54 has been opened, allowingflanged lock cover56 to be pivoted downward into the open position. Arrow A shows the motion path offront lid half40a, which can pivot forward into the closed position, or backward to rest on top of rear lid half40b. Arrow B shows the upward path of rear lid half40b, best seen in its open position inFIG. 5. With thesmart box lid30 now open, the load volume of thebox62 is revealed. Note the recesses in the inside surface oflid30, which provide 3-dimensional structural strength as well as protected, retaining spaces for electronic sensors inside thebox12.

FIG. 4 is an isometric close-up of the inside of thelid center hinge42, showing theseal strip46 and metal, notchedanti-pry latch bar74 bolted through the lid edges to lidperimeter steel band66.Hinges42 permit the top surface offront lid half40ato rest on rear lid half40b. Rubber or polymeric foamlid seal strip46 extends around the inside perimeter of lid halves40aand40b, suitably positioned to contactbox lip47 when thelid30 is closed, thus providing a good gas and water-tight seal.

FIG. 5 is an isometric of the back end of the inventivesmart cargo container12 with thelid30 fully opened, but not removed, showing the rear hinges76 attached to thecontainer lip47 via a reinforcing strap77.Lid30 remains upright because of rear hinge stops96, best seen inFIG. 6d. Withlid30 in this position, theload volume62 is completely accessible for loading and unloading cargo.

FIG. 6ais an isometric showing the top of thelid30, the transverse mid-hinges42, exoskeleton strapping44, and thecorner stacking bosses52. Note thelid bosses52 fit into bottom recesses53, as best seen inFIG. 6e.Bosses52 are suitably oriented, e.g., in diagonal mirror arrangement, to permit multiple boxes to be stacked withbox fronts22 aligned, or at 180° (ie with onebox front22 above or below another box rear28).Lid exoskeleton44, which is angled aroundlid lip64 and underneath lidperimeter steel band66, provides strength and security tolid30.

FIG. 6bis an isometric of the inventive container body hinged box exoskeleton78, comprisingfront exoskeleton panel80,bottom exoskeleton panel84 andrear exoskeleton panel82. When the molded plastic box is placed onbottom exoskeleton84, exoskeleton hinges86permit front exoskeleton80 andrear exoskeleton82 to be pivoted upward into place, and bolted through the front and back side walls of the box (best seen inFIG. 9). Likewise, thebottom panel84 is bolted through the floor of the box as seen inFIGS. 6eand9.

Visible onfront exoskeleton panel80 areslots90 forU-channel reinforcements88, such as seen on therear panel82. Tabs on the U-channel pieces fit intoslots90 and are welded into place on exoskeleton (shown installed onrear exoskeleton82 in this figure).

This feature prevents the hingedlid30 from being pried off. Aslid front half40ais lowered overbox lip47, notchedlatch74 slips over the groovedanti-pry latch pin75, securely retaining the center portion of both lid halves to boxsides24 and26. This configuration is shown in a bottom plan view, partially in section, looking upward at the side, anti-pry lid latch inFIG. 8b.

Also visible is the interior reinforcingbar68 along the inside top edge ofrear wall28, andbolts98 securingbottom exoskeleton panel84 to box bottom32.

Theelectronics bay170 for the inventive smart pallet-box cargo container is shown in the left front inside corner of the box12 (the cover panel is not shown). From bottom to top istrickle charger172,battery174 and a combined RF transceiver/microprocessor unit176, andGPS unit178, the latter being located in a recess in the top lip of the box, which is covered bypanel180. This locates the GPS out of the way of shielding exoskeleton metal. Shown in dashed lines behind the trickle charger is a female outlet for the charger plug into external power supply. Themale plug20 for external power is best seen on the upper right inFIG. 2. Themale plug20 is wired to the female plug in thebay70. The battery is trickle charged during warehousing, during transit or at its destination by plugging external 110 v power into themale outlet20. The battery powers the remainder of the electronics. Although not shown in this figure, the battery/trickle charger system can also power the audio alarm (seeFIG. 7b) andsensors196 as needed. An optional, but preferred,red LED182, seen from the outside inFIG. 2 and from the inside inFIG. 9, is also wired to the microprocessor and it lights when the system is armed. In addition, the molex connector on the bottom of the RF/microprocessor unit176 includes a lead and connector194 (seeFIG. 9) to the side wallsecurity screen array128, best seen inFIG. 10aand10b. Thus, when the screens are cut, the RF/GPS unit can signal out the event, time, and location.

It should also be understood that a wide variety ofsensors196 can be placed on the interior or exterior of the box top, bottom and side walls, or distributed inside thebox cargo volume62 and hard wire connected through a molex connector on the RF/GPS unit176. Optionally, and preferably, thesensors196 communicated their data outputs via short range RF to theunit176 to signal their state, status or an anomalous condition. Thesesensors196 may be powered by thebattery174. Preferably,sensors196 include their own battery power (typically small hearing aid, watch or camera-type disc batteries) that provide enough power for years of operation. Thesensors196 can detect, among other conditions: intrusion; ionizing radiation and X-ray; sound; light color, contrast and intensity; ultrasound (US); infra-red (IR); electro-magnetic fields; current, voltage and resistance; humidity; pH; temperature, including absolute values, change and rate of change in temperature, including both external ambient and internal; motion, such as change of direction (inertial), acceleration and speed of travel; transient vibration, displacement, inclination and shock; pressure, weight, load and force, including absolute values, change and rate of change in values; and gases, fine particulates, fumes, chemicals and biologicals, by type and amount, such as gaseous CO, CO2, O3, N2, H2, or volatile hydrocarbons, e.g., smoke, propane or gasoline, explosives, Anthrax, Ricin, and Sarin, Chlorine, Bromine, Tabun, Soman, VX, Phosgene and Diphosgene, Chlorpicrin, Hydrogen Cyanide, Arsine, Agent Orange, or other immobilizing, irritating, incapacitating or lethal gases (including single components of binary, ternary or quarter-nary gas mixtures); and the like.

In addition, thesensors196 can include snorkel tubes from the outside surface of thecontainer12 leading into totally encapsulated (sealed) sensors located inside the box or in themicroprocessor unit176. The sensors can be preset to sample parameters every one to 2 seconds up to once every several hours, and transmit updated and normal data in periodicity ranging from every 1-5 minutes or so to once per day, or only as changes or events occur. The periodicity and range of transmission may be adjusted to accommodate particular goods or conditions. Where there is no change, or the changes are within a predetermined acceptable range, the sensor can go into a sleep mode until the next programmed reading and transmission. In addition, the sensors can be polled and respond back with a reading upon request from the relay or RF/GPS or GSM unit to which they report.

As described, thesensors196 can be distributed in or on the box, or can be mounted on the PC board of the microprocessor incontrol unit176. The sensors sense conditions a predetermined value above or below a baseline value, compare and conclude that the sensed signal is an anomaly, relay that to the microprocessor in thecontroller176 which in turn further analyzes the information and packages it with other data from other sensors and the GPS system and radios it out. The RF transceiver is a transmitter and receiver that relays the information to a designated site, such as a home base or service company server, typically via a paging network (950 MHz, or other FCC designated frequency). Where the truck has a master GPS system (GSM), the RF transceiver in the box can radio to it, which packages the sensor data with its GPS then-location data of the vehicle, and relays that to the server.

The RF/GPS or GSM units can also be programmed to alert the driver. As a working example, consider a refrigerated trailer in which the inventive smart containers or the truck cargo hold includes external ambient temperature sensors. In the case where the smart containers are loaded with heat labile biological materials, such as vaccines, laboratory specimens, fresh produce or the like, when an unpermitted temperature or rise in temperature is detected in the cargo hold, the containers can be polled via the transceiver to report back the temperatures inside the individual smart boxes in the hold. Where the temperature is high or the rise exceeds a predetermined rate, the driver or other attendant can be paged so he/she can check to determine if the back door of the truck has been left open or has come ajar, or can check the compressor to determine if it has failed. Likewise, the driver can be paged if one or more containers detects an anomalous condition at any time.

Short range RF (wireless) sensors of the type useful in the inventive smart container system, having frequencies in the range of from 308 to 916 MHz and a battery life of 3-5 years, are available from Radio Data Corp of Scottsdale, Ariz. They communicate via a sensing transponder (or the transponder has its own on-board sensors) as well as being able to receive transmissions from a Radio Data Corp Universal Sensing Transmitter (USST) and other external wired sensors or status indicators. It also has a micro-controller, a 916.5 MHz transceiver, a flash memory and a real time clock (for data storage) and either an RS232/485 interface or a USB interface. This can either connect directly to a GSM, GPS/GSM or GPRS unit or it can communicate (using the 916.5 MHz transceiver to a reader that can have an 802.11, 802.15, 802.16, GSM or other global communication link. The transceiver can also be used to send local alarm signals to a Radio Data Corp Key Fob Alarm that can be worn by the driver or attendant, thereby paging them. The transponder is a collector of multiple sensor transmitter signals and the reader is a concentrator of multiple transponder signals. Radio Data Corp also provides a Key Pad Poller which allows manually coded transmissions (or instructions) to be entered into the system via either the transponder or the reader (like a parking space or loading dock number) or it can be used as a load or door status indicator.

An example of an RF/GPS unit of a type useful with thecontroller176 in the inventive smart cargo containers is a PADTAG unit available from PAD, Inc. of Longvalley, N.J., in which case the RF transmission is sent to and received by a paging or reflex network (950 MHz), and routed to a base station server. Each shipper, customer or other authorized tracker can access data on individual ones of the smart cargo containers or groups of them via a customer or user name and password on an SSL server webpage. The tracker can poll where the container is, and the location provided by the container's GPS/GSM unit will be displayed on a map. In addition, in the case of an anomalous condition being sensed, such as: unauthorized unlocking; attempt at tampering, entry or opening of the container; unlocking at an improper location; sensing temperature, humidity, chemical conditions, and the like, the system will wake up and emit an alarm, including audio, visual, sending of e-mails, faxes and phone calls, to a selected number and type of individual for response. The Radio Data Corp wireless sensors can be mounted on a Radio Data LITMIS daughter board mounted on the PADTAG controller board. An example of a commercially available GPS unit is an Earthmate GPS LT-20 unit, available from Delorme (delorme.com), or similar units from Garmin, Magellan, Lowrance and Philips.

It is preferred to include an audio alarm system in the smart container. As best seen inFIGS. 7band9, a battery-powered 90 DBaudio alarm unit184 is disposed in thefront wall22 of the container just behindspeaker grille186. This alarm is activated by simple magnetic or button typecontact switch elements188,190, in the lid and top of the box wall, respectively, as best seen inFIGS. 3 and 9. Aswitch192, seeFIG. 7b, arms or turns the alarm off. In use, after unlocking thecover plate56, theswitch192 is accessible, and is moved to the off position. Then the top30 can be unlatched via cam latches48 and opened. The circuitry is straightforward for the audio alarm, its battery, the NC magnetic switch, and the toggle switch, based on the principle that when the circuit is broken the alarm will sound.

It should be understood that thered LED182, or a duplicate of it, can be part of the audio alarm circuit. Where two red LED's are used, when both are illuminated, it means both the RF/GPS system and the audio alarm system is armed. Instead of two red LED's different colors may be used, e.g., red for the RF/GPS system and blue, white or yellow for the audio alarm. In other embodiments, the inventive smart cargo container may include a number of externally visible status or condition LEDs, the function of which is signal status including at least one of an armed condition, an open condition, a battery low condition, an attention-required condition, a wrong location warning, and a breach or damage condition.

FIG. 1ais an isometric, partly exploded view of the interior of thesmart cargo container12 showing insertion and placement of the side and endwall security screens128aand128b. A suitable security screen of fiberglass mesh interwoven with spaced, 30-gauge Tefzel-coated wire strands is available from National Security Screen, of Woodbridge, Va. Thesecurity screen127 is secured to the outside of thin, but tough, rigidplastic paneling129, such as styrene or ABS. The screen halves are suitably sized and shaped to conform to the inside dimensions of load volume ofbox62. Two halves,128aandbare placed into the box and connected at one end withwire connector132, so that any breach to the surface of the screen triggers the electronic security system which alarms, tracks and audits each specific container.

FIG. 10bis a section view alonglines10b-10bofFIG. 1aof the H-connector130 that retains the interiorsecurity screen panels128aandb. As an alternative to the hard-wired screen intrusion or wall-breach sensor, any suitable RF sensor can be used, such as one or more light or sound detecting sensor(s) capable of detecting cracks, drilling through the walls, cutting with saws, or the like. The RF sensor communicates to the controller which in turn reports the event.

FIG. 11ais an isometric of theelectronic key134 inserted in the lock plate59 (keyway).FIG. 11bis an isometric of the electronic key inserted in the T-handle type cylinder lock assembly, and rotated clockwise into the “open” position to release the lock cylinder carrying plunger122 (seeFIG. 7d).FIG. 11cis an isometric of the lock popped open upon turning the key as inFIG. 11b.FIG. 11dis an isometric of the programmableelectronic key134 showing theelectrical contacts142 which signals lock58 when the properly programmed key has been placed in thekey aperture138.

Viewing this series of figures, upon insertion ofkey134 into aperture59, thekey contacts142 engage the corresponding contacts143 of the lock. When the key code and lock code match, a green LED light143ais illuminated and the key can be turned. If a red LED143blights up, the codes do not match and the access is not authorized, nor will the key turn in the lock. Assuming an authorized key code is matched, the key134 it is turned along the path of Arrow F (the lock can be oriented so that the key has to turn either clockwise or counterclockwise, when viewed from the right side, to open). When turned, the key134 releases catch(es)126, and lock bolt or plunger release the T-handle136 (best seen inFIG. 11c), is spring-biased to move outward along Arrow G (inFIG. 11b). That allows locking pin (plunger or bolt)122 to be pulled out oflatch plate hole120 oflatch plate108. The lock is now opened and thelock cover56 can be rotated down to provide access to the cam latches48.

Note that only when the lock and key code match (green LED signaling match) can thetang148 of the key be rotated to release thecatches126. Releasinglatch plate108 permitsflanged lock cover56 to open, which in turn permits lid latches48 to be released for access intobox interior62. By way of example, a suitable electronic lock is the “NexGen” electronic high security lock system, available from Medeco Inc. of Salem, Va., USA, a division of Hillenbrandt Industries, Inc. The NexGen electronic lock provides access control, audit capability, route management and the physical security of a high quality mechanical lock. No hardwiring is required of the lock because it derives all of its power from the programmable key, which is battery powered to last for up to 4,000 or more audit events. The software system permits the user to program into the key, authorization who may open the lock and when they may do so. Upon download of data from the key, the software program provides detailed reports for complete security management, including all openings and attempted openings. Because the keys are electronically reprogrammable, locks and keys can be immediately rekeyed to replace lost or stolen keys. A single key can access up to 11,000 differently programmed locks, and each lock can store up to 2,000 audit events. While the electronic keys are currently available in four different styles, each is designed to be able to open T-handle cylinder, cam or padlock style locks. In the instant smart pallet-box cargo container, the T-handle type cylinder lock is preferably employed.

As seen inFIG. 11dthe programmableelectronic key134 includes spring-biased protruding pin-typeelectrical contacts142 which signallock58 when the properly programmed key has been inserted in the key aperture138 (also known as a “plug face”) to align with the respectiveshallow recess contacts145 in the lock. As described, when electronic “recognition” between lock and key has occurred, the green LED lights, and when there is unauthorized attempt, the red LED lights. Theside grooves150 retain the key in proper orientation in the programming cradle (best seen inFIG. 11e), for programming (pre- and re-programming)key134 via the contacts on the opposite side of the key, as seen inFIG. 11b.

FIG. 11eis an isometric of the hardware for configuring use authorizations and audit trail downloads of the electronic key of the inventive smart cargo container.Key134 is resting incradle152, its cradlepin retaining grooves150 aligning it to the cradle's pins154.Programming contacts146, seen inFIG. 11b, are not visible in this view, as they are on the underside of the key134, aligned with programming contacts located incradle152. Programming is performed using a laptop ordesktop computer156, shown here withstandard mouse158 and monitordisplay160. LED lights144 (seen also inFIG. 11b), one red and one green, light when the programming is in process (red) and complete (green). Alternatively, the programming can be done by use of a hand held PDA or tablet computer. In addition, the red/green LEDs144 can be amber/green or any other color combination, and can indicate the key is downloading the accumulated data from its memory and download complete, or the like suitable code.

The electronic locks have a hardened steel shell (thebody126, bolt orplunger122, release T-handle orhead136 and plugface138 as shown inFIG. 11c), and the keys electronically record in included memory (for example, flash memory) on the order of thousands of separate auditable events, including at least one of: opening attempts; failure to open; positive open events; time of event; and the duration that the lock is in the open state. In addition, the keys can be programmed at home base (seeFIG. 11e), or in the field by laptop, PDA, cell phone (including Blackberry or Sidekick) and the like devices, and the programming configuration code can be provided from a remote center to the programming cradle driving device (laptop, PDA, cell phone, etc.). The keys can be programmed to open locks only within specified time parameters. Each key is uniquely identified, both electronically and by bar code strip on the side or face of the key, so that they can be issued on a restricted basis to only authorized personnel, and they can be accounted for. When the key is inserted in the lock, the lock memory can download to the key, so that upon putting the key in the programming cradle the lock history data can be downloaded to the computer system for analysis and reports.

The electronic keys useful in the inventive smart box, need not have physical contacts as in the above described, non-limiting example, but may be activated via a RFID system to provide the key/lock recognition/authorization functionality permitting the key to be rotated in, or otherwise open, the lock. In addition, the lock may contain within itsbody126 or within the housing116aflash memory drive to record a wide variety of events related to the lock, such as the ones enumerated for the key, or the condition status of the box.

In another important alternative embodiment, a GPS unit is incorporated in, or electrically connected to the lock or the key to provide a second level of access control, in that the lock is programmed so that if it is attempted to be opened at other than a pre-determined, pre-programmed destination, the lock will not open. Thus, upon the key being inserted in the lock, the then-GPS coordinates are checked and compared to the programmed location in the memory of the key or lock, and if they compare, the green LED lights or flashes and the lock can be opened. As in the above example, if the coordinates do not compare within a preselected margin of error, e.g., within the accuracy of the GPS unit (within a few feet), the lock will not open. In either event, the history record will be stored for future download, or real time reporting by RF, e.g., Pager, Cell Phone, Bluetooth or other wireless network. Thus, the unauthorized event can be reported in real time to on site, near-by local, regional or distant location, by direct RF, or via RF to a local WAN or LAN wireless (e.g., 802.11-type) router that communicates via the Internet to a server at the shipper's, customer's, or security service (including governmental, military or law enforcement) headquarters or service center for appropriate action.

FIG. 12ais a schematic block diagram of the architecture of the controller and data communications system as employed in the inventive smart cargo container, andFIG. 12bis a schematic of the system and operational architecture of the remote electronic tracking and security condition reporting by the inventive smart container. The smart container data communication and management system includes sensors, locks, alarms, container armed status lights, data encoders, transmitters and/or transceivers, computer programs, data bases, and related equipment to enable activation, coding, decoding and use of the data communications system, including real time and past history display of status and location, and management and operation report generation. The inventive smart cargo container monitoring and management electronic data communications system includes container-mountedcomponents200, separate remote signal relays (towers198, satellite208), monitoring station components210, and auxiliary equipment including locators (GPS locators)178 and lockingsystems54. The home base monitoring station210 includes a computer system having a CPU162 in which is loaded data engine, display programs and web server or web browser programs to enable activation, operation and use by customers of the data system.

As seen inFIG. 12a, thecontainer12 includes acommunication module200 which comprises a programmable Peripheral Interface Controller (PIC)214 mounted onmicroprocessor controller board176, abattery174, a transmitter or transceiver (transmitter/receiver)212,trickle charger172 connected to the external power viaoutlet20, and a wide range of inputs (lock54,security screen128,GPS178, sensors196) as well as I/O ports216 for configuring the programmable PIC by computer, and outputs including selected frequency command signals for short or limited range RF broadcast218a(e.g., to a master GSM, transponder, transceiver or repeater, unit in the truck, warehouse or via a reader as the truck passes a way station), or longer/full range RF broadcast218b(e.g., to pager or cell network towers or satellites)audio alarm184,status LEDs182, and others,216. The container location and status data can be sent as text, and can include a time stamp. The PIC can conserve battery use by turning the radio on just before a transmission will be sent, and can be configured to transmit a ⅓ second position burst after container data input, or to send container status/condition data on command from home base or at cyclic intervals. The PIC operating parameters are stored in its internal EEPROM that is configured from computer system162 at home base210, and will persist even when power is removed.

The remote monitoring aspects of the invention provides a method for shippers, customers, and security/audit personnel to monitor from a single “home” base, many containers simultaneously, the number ranging easily in the thousands. Under the inventive system, the tracking personnel can be notified and check when anomalous events occur and can have a complete handling report for each container from empty before loading to empty upon unloading at its destination, and with confidence in the security of the container along the route, including in the transport vehicle (truck, ship, rail, aircraft), in its origination facility, warehouses or transfer depots along the way and to destination unload or storage.

The inventive security system provides a unique identifier for each container in the field that is radioed to home base when the container is first put in use. Each container is pre-configured at home base (e.g., home warehouse, customer or shipper facility, manufacturing facility or the like), or in the field via the PIC program with a unique identification number or other data (name of customer, shipper, type of goods permitted to be shipped, etc), and its cycle of time for status reporting is pre-selected at that time. After loading and closed, it is initialized or enabled, and thereafter the container reports its status, the time, or/and location back to home base on the predetermined timed cycle, e.g., every half-hour, more frequently at night, less during the day, etc.), or to pollers (very short range, long-life battery powered microprocessor-controlled RF transmitters that are placed at various sites around the warehouse, storage facility or customer location), or readers (long range, 100-1500′ depending on antenna) transceivers with the ability to receive an interpret the data from the container transponders and then forwarding this information by wired or wireless communication to a computer or computer network for real time location and status data retrieval from the containers). The program at home base displays a map from the map program with each container or group of containers located thereon with a unique icon, and the status can be indicated in text or change of icon, e.g., by animating the icon, changing color, flashing, change of text, combinations of them, and the like. In addition, an audio alert signal can be emitted on the computer speakers when the sensor or lock detects an anomalous event or unauthorized, untimely, or wrong destination attempts to open the container occur.

The inventive computer-enabled smart cargo container system permits complete management of the container security during transport, storage, loading and delivery, as a business, including communication via the Internet of container status and event reports, orders, billing, e-mail communications, and the like. In addition, the status reports of each container can be viewed and printed out for analysis, or can be computer-analyzed to show status and anomalous events, including access opening and locking, related by time of day, customer, shipper, by location, and the like. The accumulation of container handling data for a particular site, particular customer, particular shipping line, particular type of goods, and the like, over time can also be analyzed to reveal changes in commerce, types of events, patterns of attempted theft or damage, reduction in theft, and the like.

The inventive communication system includes provision for a wide range of inputs for any given container or type of goods being shipped or stored therein. That is, the PIC can accept a variety of sensor inputs, both interior of the container and external to it, by placement of appropriate sensors that are well known in the art and commercially available. For example, IR and US sensors, microphones, bolometers, thermometers, humidity, pressure, and surveillance optics (some as small as coin sized) are readily available. Following the principles taught herein, one skilled in the art will easily be able to mount any selected sensor(s) and hook them to the PIC for transmission of the sensed data back to home base for display or storage in the computer database. In the embodiment(s) in which atransceiver212 is mounted in the container, the home base can selectively poll individual sensors for readings, or the PIC can be programmed to provide selected readings on a timed cycle. For example, upon receipt of a signal from thesecurity screen128 that it has been breached, or from themagnetic sensors188,190 that there has been an attempt to jimmy the top of the container, the PIC can be programmed or a signal can be sent from home base to turn on a microphone and/or camera to ascertain more data about the event, or to collect law enforcement or prosecution evidence.

Typically, theRF transmitter212, or the truck-mounted master GSM unit, transponder, transceiver, orreader206 in the cab or in the trailer (seeFIG. 12b), sends a data burst lasting less than a second and is only powered when sending; that is, thetransceiver212 is OFF until the programmedPIC214 sends a wake-up signal (power enable signal) to the transmitter for the transmit burst. The PIC is preferably configured to send an event occurred signal immediately upon the event, rather than wait for the next cycle. The PICs of different containers in a given cluster, e.g., warehouse or truckload, are preferably configured with different cycle send-times so that no two containers send simultaneously to home base.

By way of example only, since the bursts typically last less than a second the theoretical number on a single frequency is 3600 repeated hourly, but typical is every 30 minutes for 1800 container capacity. It is also possible to set thecontainer comm module200 to repeat the burst in time-spaced intervals, say once each 5 seconds for 3-6 tries, so 1 minute spacings between different container reports is more typical. As an alternative to the pager network frequency of 950 MHz or cell phone frequencies (any one of the quad mode frequencies available worldwide), a useful RF frequency is one of the no-license required frequencies of 154.600 MHz±5 kHz (Green Dot), and 154.570 MHz±5 kHz (Blue Dot). However, dedicated licensed frequencies can be obtained for use through an FCC-licensed Frequency Coordinator. Thus, different containers of different customers or shippers can communicate by different frequencies, so the real-time monitoring of thousands of containers simultaneously is entirely feasible under the inventive system.

As shown inFIG. 12b, the transceiver/transmitter-containing in-container module200, or the in truck transmitter/repeater/reader206 can transmit to tower198 orsatellite208. In addition, they can receive as well from either of them, including the GPS coordinate system viasatellite208. Thetransceiver212 of home base210 receives the signals, processes them as described above and displays the text data or map data onmonitor160, or prints a report on the printer168. The system is interactive via peripheral input devices, such asmouse158 and keyboard164. In addition, the CPU or server162 (in the case where home base is a tracking service center server) can communicate via hard wire (DSL, fiber, cable, etc)220aor wirelessly220bto the Internet, to access by browser or serve pages that are accessible by the service center customers, e.g., shippers, customers and security service and tracking personnel. That is, the home base of a customer does not need to have a transceiver for direct receipt of the reports. Rather, the customer can access a service center site, enter a customer number and password, and then be served and have access to pages on which that customer's container status and history reports and present location maps are displayed. In addition, the service center can automatically enable event alerts by e-mail, fax, or telephone to the customer. The service center can also alert the driver or vehicle/warehouse attendant(s) to check as events occur and warrant. The receiver in the container can be interrogated (polled) from home base requesting reports of available data.

The computer system162 is powered by AC or in the case of a laptop or PDA, by a suitable battery. The computer system at home base (or a portable, such as a laptop or PDA) is loaded with suitable operating system, applications programs, Internet browser(s), image transfer and e-mail programs. By way of example, a packet engine program and an APRS program with map data are employed to decode the RF transmission from the containers in the field, and to display the location, identification and status (at identified time/date stamps) of each container, as well as set the parameters for reporting the container status on a timed cycle. A suitable software-only packet engine is the AGWPE program available as shareware (for a contribution license fee) from www.raag.org/sv2agw/pepro.htm, which permits receipt of the data from thereceiver212 directly into the sound card of the computer. Alternatively, a packet modem can be used to convert thereceiver212 signal to digital data for input to the serial port of the computer system162. The AGW Sound Card portion of the AGWPE program permits tuning the audio signal, permitting setting of the volume and squelch of the input signal fromreceiver212, in cases where audio alerts of anomalous events is desired.

A suitable display driver for the map display feature of the inventive system is an APRS application program, available from www.winaprs.org. These programs are available in Windows, Mac and Linux operating systems, as WinAPRS, MacAPRS and XAPRS, respectively. These two programs function as the interface that takes the data from the sound card or the packet modem into the packet engine and the APRS places the trap location/status data on the map program.

Any suitable map data that interfaces with (becomes embedded in) the selected APRS program is used to provide map images. Suitable sources of map data includes: Tiger Maps, which is Census Bureau map data available from www.census.gov/geo/tiger/. Other sources are US Geological Survey, NASA, Delorme maps, Microsoft MapPoint and Microsoft Streets and Trips.

In addition, the computer system can be configured to communicate via theInternet202 selected data for operation of the container security system as a computer enabled Internet-based business. This includes reports, communications and billings to remote clients or associates, franchisees, regulatory agencies, law enforcement, shippers, customers, and the like. It permits a central home office to communicate with regional offices or remote warehouses or shipping depots. Local, regional or national “views” of shipping and container security activity, such as the real time shipping loading, unloading, access and sensor events, can be communicated automatically to the remote home offices, permitting a nation-wide management operation.

Thus, the computer-enable Internet system of this invention includes a base station including a transceiver for receiving RF signals from the smart cargo container RF transceiver, and a computer system including: a web server for securely serving pages to clients and a CPU and memory that includes operating and applications programs that receive, analyze, serve and save, in at least one database structure, time-related and real time security status and location data from a plurality of said containers, including pages having annotated map information of the container identification, map location and movement and event alerts; and at least one client smart cargo container monitoring computer system that includes a CPU, memory, at least one display, and input/output peripherals, said CPU and memory including operating and applications programs that cause the client computer system to access the Internet and receive web pages served by the service bureau base station server upon entry of client authorization data, these web pages including at least the real time and time-related security status and location data about containers for which the client has authorization to monitor, in graphical or text format.

The computer systems of either or both the tracking service server or the customer can include a database of the history of handling of each container tracked and serves that history to the client upon request. This history includes at least one of: a unique identifier for each container; opening attempts, times and durations; personnel authorized to open a container; electronic lock configuring information; handling locations and times comprising shipping and storage events; anomalous events sensed by container sensors; ownership of each container; identification of shipper and customer for each shipping and storage period; nature or type and amount of goods shipped or stored, and the times and periods involved, and the like. That is, any history deemed relevant by the customer can be harvested, stored in a database, retrieved and displayed.

INDUSTRIAL APPLICABILITY

It is clear that the inventive smart pallet box cargo container provides a commercially significant system for better security and handling history and real time tracking of sealed containers for transportation, and especially for long haul trucking, and at the same time provides for improved security of the goods being shipped, thereby reducing damage and theft losses during transport and warehousing. Either advantage alone is both substantial and important to the shipping industry, and of great significance to the manufacturers and shippers of goods in commerce. The smart cargo container, in being unitary, that is, in not having loose parts that can become lost or non-functional, provides additional advantages for commerce. Further it permits the possibility of direct selling out of the box, without the need for intermediate packing in cardboard cartons.

As such, the inventive smart cargo container for shipping and warehousing is applicable to all industries involved in transport and warehousing of goods, especially high-added-value goods, such as pharmaceuticals, consumer electronics goods (computers, home electronics, etc.), electronic parts (computer components, chips, memory boards), entertainment products (such as CDs, DVDs and Video Tapes), and goods requiring high security transport (such as pharmaceuticals, mail, biological specimens, proprietary information) and the like.

It should be understood that various modifications within the scope of this invention can be made by one of ordinary skill in the art without departing from the spirit thereof and without undue experimentation. For example, the containers may have more or less than 4 walls or have the particular geometric footprint shown. Thus they could be round. Likewise, the containers can be modified for special lifting modes, such as side or top hooks or recesses for handling by other than forklifts from the bottom. Thus, the feet for forklift access are not an essential limitation of the invention. This invention is therefore to be defined by the scope of the appended claims as broadly as the prior art will permit, and in view of the specification if need be, including a full range of current and future equivalents thereof.
